Description

Flushing channel device for fish tank

The present invention relates to a rinsing channel device for a basin, in particular a sink or washbasin, having a profile assembly, according to the preamble of claim 1 .

The invention also relates to a water tank, in particular a sink or washbasin, having a rinse channel arrangement.

Water baths of various embodiments are known from the prior art. In particular, a sink for use in a kitchen and a washbasin for body care can be modified in various ways. Such water baths are used, for example, in the household, industrial and medical sectors.

In most cases, hygiene, especially the sterilization and cleanliness of the water bath, is of paramount importance. Therefore, the water bath must be thoroughly cleaned on a regular basis.

Most sinks and washbasins have a water inlet through a fitting to distribute water from a central jet. However, the central injection of water is detrimental to complete and thorough cleaning inside the water tank.

To aid in cleaning, fittings with an extensible and flexible hose are known. However, they are relatively expensive to produce and may require repair. Moreover, since it is not uncommon for the visual design of a fish tank (especially for home use) to be of high importance, flexible fittings also impede the design freedom of the fish tank and fittings.

To facilitate cleaning of the water bath, the general document DE 10 2010 021 541 A1 proposes a water bath designed so that, at least in certain areas, the upper water bath rim distributes an additional amount of water. For that purpose, an inner receiving area is formed in the upper cistern rim with a gap open downwards in which an annular water dispensing appliance is placed, which is enclosed in the manner of a pipe. On the circumferential surface, the water dispensing device is provided with several nozzles capable of dispensing a certain amount of water.

A similar bath is also disclosed in DE 1 934 095 U. DE 1 934 095 U proposes that the main feed line for the fitting of the cistern runs around the rim of the upper cistern in an annular fashion and is drilled with individual holes.

In this way, the inner or side walls of the water bath can be selectively rinsed. This is to reduce the complexity and frequency of manual cleaning.

However, the water dispensing devices known in this regard have only been found to be conditionally suitable for cleaning water baths. Because the water is distributed in a nozzle-like manner at certain points, a very uneven flow occurs along the sidewall of the tank. As a result, uniform and thorough cleaning cannot be guaranteed. Uneven distribution of water ultimately means that additional visual contamination, such as limescale, can occur along the sidewalls of the tank.

Due to the drawbacks described, water baths of this type have not been fully implemented to date despite the high demands on hygiene and cleanliness. This is what the present invention is intended to achieve.

In view of the known prior art, it is an object of the present invention to provide a rinse channel device to enable improved cleaning of a water bath or at least to assist in the cleaning of a water bath.

The present invention is also based on the object of providing an improved water tank, preferably a self-cleaning water tank or at least an easy-to-clean water tank.

The object is achieved with a rinsing channel device having the features disclosed in claim 1 . Regarding the water bath, the object is achieved by the features of claim 25 .

The dependent claims and features described below relate to advantageous embodiments and variants of the invention.

A rinse channel device for a water bath is provided that includes a profile assembly having an interface or multiple interfaces for supplying liquid to a distributor line of the profile assembly and a dispensing region for dispensing liquid. .

The interface may be a port and/or an aperture, in particular for a liquid feed line.

The proposed rinse channel device is particularly suitable for use as a sink or washbasin. However, in principle the rinse channel device may be suitable for use with any desired water bath requiring rinsing or cleaning. For example, the water bath may also be in the form of a bathtub, shower tray, hairwashing water bath or other water bath, but in particular a water bath for washing body parts, plants (plant parts) and/or objects. may be in the form of

The liquid may preferably be water (in particular drinking water or tap water), optionally comprising further substances or additives. In principle, any desired liquid suitable for rinsing or cleaning the bath can be provided, for example specially provided cleaning liquids.

Preferably, the same liquid that is also used for the normal operation of the water bath is supplied to the rinsing channel arrangement, but optionally with the further substances or additives mentioned.

According to the invention it is provided that the profile assembly comprises a flow channel extending from the distributor line to the distribution area along the channel path. The distributor line, the flow channel and the distribution area extend through the profile assembly along a longitudinal axis of the profile assembly.

The inventor has recognized that when the aforementioned flow channel is formed between the distributor line and the distribution area, the liquid is distributed from the rinse channel device in a manner particularly suitable for washing the water bath or rinsing the water bath.

In contrast to known "self-rinsing" water baths where water is dispensed directly from the distributor line through separate nozzles or orifices, the flow channels allow for a more uniform laminar flow, consequently the water bath Uniform wetting of the inner side can occur. In this regard, it has been shown that the uniform distribution of liquid when the bath is rinsed essentially contributes to the disinfection and overall cleanliness of the bath.

In one development of the invention, it can be provided that the interface for supplying the liquid has an aperture in the side wall of the profile assembly extending along the longitudinal axis.

The interface may also include, for example, a coupling for connection of the liquid supply line (eg a rigid or flexible pipe), the liquid supply line being connected to the profile assembly as part and/or as a whole of the liquid supply line. coupling) may be included.

In principle, any desired number of interfaces may be provided, for example exactly one interface, two interfaces, three interfaces, four interfaces or more interfaces, distributed along the longitudinal axis of the profile assembly. (e.g. uniformly or equidistantly distributed).

However, preferably exactly one interface is provided, which facilitates the connection of the rinse channel device to the already existing sanitary infrastructure.

The distributor line of the profile assembly can advantageously contribute to a uniform distribution of the liquid along the longitudinal axis of the profile assembly or within the rinse channel device.

According to one refinement of the invention, it may be provided that the channel course is aligned orthogonally to the longitudinal axis of the profile assembly.

It should be mentioned that the longitudinal axis of the profile assembly should not have a straight or linear path. Preferably, the longitudinal axis has a curved path or at least a curved part, in particular to follow the path of the side wall of the water tank.

The channel path preferably also follows a straight or non-linear path and has at least a curved portion, for example at least a bend as will be explained below. In this way, the channel path can preferably form at least one loop (preferably multiple loops).

According to one refinement of the invention, it can be provided that the distributor line has a distributor channel diameter (or distributor channel width) greater than the maximum channel diameter (or maximum channel width) of the flow channel.

As long as “diameter” is mentioned in the present case, it is in principle possible to mean the diameter of a circular or at least approximately circular channel/line. However, what is meant may also be the height and/or width of a channel/line of any desired cross-section, for example a rectangular cross-section. Accordingly, the term “diameter” should not be explicitly understood to mean a circular cross section.

As a result of the fact that the distributor region has a larger channel diameter or a larger channel width than the flow channel, the distribution of the liquid along the longitudinal axis of the profile assembly can be improved. Accordingly, since the distributor line can accommodate a relatively large amount of liquid, it can serve as a buffer or a reservoir.

In one development of the invention, it may be provided that the distributor line merges with the flow channel along a cross-sectional narrowing.

Preferably a uniform cross-sectional narrowing, in particular a linear cross-sectional narrowing, is provided. Thus, turbulence when dispensing the liquid can be substantially prevented.

In an advantageous development of the invention, the distributor line comprises a distributor element, which is intended to guide the liquid supplied through the interface in at least two different directions (eg the longitudinal direction of the profile assembly). disposed in the region of the at least one interface via the distributor line (in opposite directions along the axis).

This makes it possible to distribute the liquid more evenly in the rinsing channel arrangement. In particular, unfavorable turbulence or swirling can be avoided, or at least their occurrence reduced.

An individual interface may in principle also contain multiple distributor elements. As long as multiple interfaces are provided for supplying liquid, each interface can preferably be assigned to at least one dedicated distributor element.

The distributor element may be disposed within the interface or secured to the interface. However, the distributor element may also be arranged within the distributor line in a manner adjacent to the interface.

According to one development of the invention, it can be provided that opposite the interface in the direction of supply of the liquid, in particular the distributor element is arranged on the inner wall of the distributor line.

The distributor element may include a tip or tapering edge aligned in the direction of the interface. The distributor element preferably has a wedge-shaped shape with a linear or concave curved wedge profile. Pyramid shaped distributor elements may also be provided.

In one development of the invention, it can be provided that the distribution area is in the form of a distribution slot extending along the longitudinal axis of the profile assembly.

In particular an adhesive dispensing slot extending along the longitudinal axis of the profile assembly can lead to a particularly uniform distribution of the liquid in the bath. However, if appropriate it is also possible for multiple non-adhesive dispensing areas, in particular dispensing slots, to be provided, for example one dispensing area for each side wall of the cistern.

The distribution slot preferably has a distribution diameter or distribution width smaller than the minimum channel diameter/minimum channel width of the flow channel.

Since the distribution diameter, or the distribution width, is smaller than the channel diameter/channel width of the flow channel, the distribution area forms a kind of elongated nozzle. The distribution amount and flow rate of the liquid distributed through the distribution area may be settable by the distribution diameter or distribution width.

In an advantageous development of the invention, the dispensing diameter, or the dispensing width, is approximately or exactly between 0.1 mm and 2.0 mm, preferably between 0.3 mm and 1.5 mm, particularly preferably between 0.5 mm and 1.0 mm, for example 0.8 mm. can be provided.

The areas mentioned above have proven to be particularly suitable since they are possible for a particular dispensing diameter, or dispensing width, and are preferably determinable depending on the pressure used to supply the liquid (in particular with respect to the pressure in the liquid supply line). The values mentioned above are particularly advantageously suitable for use with normal household mains pressures of about 3 to 4 bar.

In one refinement of the invention, it can be provided that the dispensing area comprises an extensible diaphragm, for example a rubber lip.

The extendable diaphragm is preferably designed to close the dispensing area when liquid is not being dispensed from the dispensing area.

An extendable diaphragm may optionally further improve hygiene of the rinse channel arrangement, as it may prevent dirt and/or germs from entering the distribution area.

In an advantageous development of the invention, it can be provided that the flow channel forms at least one bend, preferably at least two bends, particularly preferably at least three bends, along the channel path. . The flow channel preferably has a loop-like path.

Surprisingly, it has been found that it is possible to create a particularly suitable and uniform laminar flow for rinsing the water bath, in particular by using a bend, or a loop-like path of the flow channel.

The looped path, or bend(s) may also provide a flow channel such as a siphon, so that an odor trap may be provided at the same time and/or dirt or dust may be introduced into the rinse channel. The introduction of germs can be avoided.

In an advantageous development of the invention, it can be provided that the flow channel has a smaller cross section along the bend.

This makes it possible to further optimize the flow behavior of the liquid.

The cross section of the flow channel along the bend preferably corresponds to the aforementioned "minimum channel diameter" or "minimum channel width" of the flow channel. A cross-section of the flow channel along a (generally) linear or straight section between the bends may preferably correspond to the "maximum channel diameter" or "maximum channel width" mentioned above.

In an advantageous and advantageous development of the invention, it can be provided that the distributor line, the flow channel and the distribution area extend over the same length along the longitudinal axis of the profile assembly.

As an alternative, however, it may also be provided that the distributor line, the flow channel and the distribution area do not extend over the same length along the longitudinal axis of the profile assembly. For example, it may be provided that the distribution area extends over one or several sub-regions along the longitudinal axis of the profile assembly.

In one development of the invention, it can be provided that the profile assembly has an essentially closed or at least substantially closed path along the longitudinal axis.

The profile assembly preferably forms a completely enclosed ring or is completely closed around its periphery. In this way, it is possible to rinse the entire periphery of the water bath.

According to one refinement of the invention, it can be provided that the profile assembly has a single-part or multi-part form.

The determination whether the profile assembly is of single-part or multi-part form can be made in particular in view of the production process, the starting material of the bath and the starting material of the rinse channel device. Generally, a multi-part construction of the profile assembly is preferred due to the production process.

The profile assembly may have a single-part form, in particular when the rinse channel device is integrally formed with the water bath.

In an advantageous development of the invention, it can be provided that the profile assembly comprises a first profile part and a second profile part, which when connected to each other form the distribution area, the flow channel and the distributor line (appropriate if available, with the above water bath).

In principle, it is also possible to provide further profile parts, for example a third profile part, a fourth profile part or more profile parts. However, the construction of multi-part profile assemblies consisting of exactly two profile parts has proven particularly suitable for the purpose of establishing optimum conditions between economical production and easy mounting.

It may also be provided that the cistern or a component part of the cistern, for example one or more inner walls or side walls of the cistern form one part of a (multi-part) profile assembly. For example, the distribution area may be formed from a profile part of the profile assembly and a side wall of the water tank.

In an advantageous development of the invention, it can be provided that the distribution area, the flow channel and/or the distributor line comprise a rib operating between their respective side walls.

The rib preferably runs at least in a specific portion along the channel path. The rib makes it possible to define the flow of liquid through the profile assembly for one part and to improve the stability of the profile assembly or the rinse channel device for another part.

In an advantageous development, it can be provided that the rinsing channel device comprises at least one feeding device for feeding the additive into the liquid.

The additive may be, for example, a cleaning substance, such as a rinse, hygiene product, disinfectant and/or a descaler. This makes it possible to functionally improve the rinsing of the water bath by means of the rinsing channel arrangement, for example to improve the cleaning action of the rinsing.

According to one improvement of the invention, it can be provided that the feeding device comprises a reservoir for providing the additive.

The reservoir is preferably manually fillable or supplied from a supply line.

In an advantageous development of the invention, it can be provided that the feeding device comprises a conveying device for conveying and metering the additive, in particular a pump and/or a Venturi nozzle.

The pump may be an electric pump and/or a mechanical pump, for example a foot operated pump.

The feeding device may also include an electrical and/or mechanical valve to meter the additive according to requirements or to stop feeding according to requirements.

The pump, the valve and, where appropriate, the venturi nozzle may be actuated mechanically and/or electronically. Optionally, automated open-loop or closed-loop control may be provided. However, purely manual operation is also possible.

It may also be provided that the rinsing channel device comprises a conveying unit, in particular a pump, for conveying and/or metering the liquid. Liquid may be supplied to the rinse channel device from a reservoir or liquid store together with liquid for the normal use of the water bath, or it may be supplied separately from them.

Dispensing with each pump is selectively possible as long as the reservoir for the additive or the reservoir for the liquid, or the liquid reservoir for the liquid, is arranged on a higher level.

In an advantageous development of the invention, it can be provided that the rinse channel device is in the form of a component part of the water bath or an insert for the water bath.

According to one refinement of the invention, it can also be provided that the profile assembly is provided with an antimicrobial coating which affects a specific area or completely, preferably the interface, the distribution area and/or the flow channel. The antimicrobial coating may be, for example, a nanosilver coating.

In this way, even when the rinsing channel device or the water tank is not used for a relatively long period of time, the formation of a biofilm can be prevented and sterility can be ensured.

In one development of the invention, it can be provided that the rinse channel arrangement comprises a control device configured to control and/or monitor the distribution of liquid from the distribution area, preferably depending on a user input.

The control device is capable of communicating (wired and/or wirelessly) to electronic components of the rinse channel device, such as pumps, other actuators, sensors, radiation sources as described below, evacuation devices as described below, or other devices. can be connected

The control device may include a user interface to enable user input and/or read statuses and measurements from a user of the rinse channel device or the vat. The user interface may include a display device, eg a screen, and/or an input device, eg one or more pushbuttons. Although it is possible to use any desired wireless standard, particularly the Bluetooth standard, WLAN standard, Zigbee standard, GSM standard or other wireless standard, it is preferred that a wireless user interface is provided, particularly within the ISM band. The user interface may include a web application and/or an application ("app") on a mobile terminal.

The control device may comprise a data interface through which the control device is connected to a database and optionally an external computer unit. In particular, the data interface can provide an Internet connection, so that the control device can be connected to a cloud system, for example.

The control device may preferably be configured to plan and manage the cleaning cycle according to an automatable schedule regarding the start, end, duration and/or intensity of the cleaning cycle. It is also possible to provide monitoring of the fill level and the like.

In one development, the rinsing channel arrangement preferably comprises a supplied liquid (washing liquid and/or liquid used in the normal operation of the water bath) for the purpose of self-sufficient power supply to the electronic components of the rinsing channel arrangement. It may be provided to include a generator arrangement for partially converting the kinetic energy of the motor into electrical energy. In this way, it is possible to control the rinse channel device without access to electrical connections.

The generator device may in particular include a water turbine and a generator connected to the water turbine.

Optionally, an electrical energy store such as a rechargeable battery pack may be provided to store electrical energy generated by the generator device. Electrical energy stores, in particular exchangeable or rechargeable energy stores, may serve as a comprehensive alternative to generator units. In this way, the rinse channel device can operate autonomously for at least a period of time.

The generator device can advantageously be arranged immediately upstream, downstream or at the interface of the profile assembly. However, arrangements of supply lines or distributor lines to the interface may also be provided. It may also be provided for connecting the generator device to any desired liquid supply line of the water tank - where appropriate to the liquid supply line and to an existing fitting of the water tank (eg to an angle valve in a building, for example). The generator unit may in particular include a 3/8 inch coupling to connect to the liquid supply line.

The present invention also relates to a water tank, in particular a sink or washbasin, comprising the rinse channel device according to the above and below statements.

Advantageously, a self-cleaning recirculation rinse channel bath may be provided. According to the present invention, since dust, food residues, germs, etc. falling into the water tank cannot generally accumulate on the side walls, they can be easily washed or removed by the rinsing channel device. Thus, once dust adheres to the side wall of the water tank, it can be easily removed later. Thus, the bath is capable of self-cleaning, or at least supports manual cleaning.

According to the present invention, hygiene can be significantly improved in a wide range, for example in hospitals, nursing homes, medical practices, laboratories, private homes and the food industry when the water bath is operated. For example, the possibility of infection and contamination of sinks or washbasins can be significantly reduced according to the present invention.

The rinse channel device may be adhesively bonded, screwed or otherwise releasably or non-removably connected to the cistern. As already mentioned above, it is also possible that the rinsing channel device and the water bath are provided in one piece.

The rinse channel device for rinsing the water bath may be mechanically and/or electronically activated.

The rinse interval or multiple rinse intervals for rinsing the water bath using the rinse channel device are preferably freely selectable and can be defined, for example, by means of a timing circuit.

For actuating the rinse channel device, in particular the control device described above may be provided for controlling valves, pumps, electromechanical nozzles and/or for evaluating sensors and actuating switches, for example.

The control device may be in the form of a microprocessor. Instead of a microprocessor, any desired additional device for implementing the control device, for example a printed circuit board, a storage-program controller (SPC), an application-specific integrated circuit (ASIC) or other programmable circuitry, for example a field It is possible to provide one or more arrangements of programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and/or discrete electrical components in a commercially available computer.

The bath may be made of metal, in particular metal sheet, ceramic and/or plastic material. The bath may also preferably be made of a composite material, for example a quartz composite material. Of course, combinations of various materials are also possible. In principle, the water bath can be made of any desired material.

The rinsing channel device, in particular the profile assembly of the rinsing channel device, can preferably be made of a plastic material. However, in principle the rinse channel device or the profile assembly can be made of any desired material, for example metal. Of course, combinations of various materials may be provided.

It may be provided that the dog's sidewall or all sidewalls are designed to be rinsed with the liquid dispensed from the dispensing area.

The rinse channel arrangement is particularly preferably arranged in the water bath in such a way that the rinse channel arrangement is able to rinse the water bath entirely inside.

In principle, the water bath may include any desired optional components, in particular a liquid outlet for the liquid (outflow, downpipe and/or siphon), an overflow for the liquid, a deposition surface, and the like. can include

In one improvement, it can be provided, in particular, that the water tank comprises a fitting supplied by the main supply line (in particular with drinking water or tap water).

The main supply line is preferably fluidly connected to the liquid supply line and/or to the interface of the rinse channel arrangement, for supplying the same liquid to the water tank through the fitting and the distribution area of the rinse channel arrangement.

It is possible, preferably together with the liquid supply line, that the liquid supply by the rinse channel arrangement is adjustable by means of the fitting, for example to enable simultaneous or synchronous dispensing of liquid from the fitting and the rinse channel arrangement. A fluidic connection between the main supply line and the liquid supply line is disposed downstream of the valve of the fitting in the flow direction, for example to regulate the distribution of liquid from the rinse channel device through the valve of the fitting. It can be.

However, the fluid connection between the main supply line and the liquid supply line is preferably arranged upstream of the valve of the fitting in the direction of flow, integrating the rinse channel arrangement into an existing water tank, or using the rinse channel arrangement with an existing fitting make it easier to do In this case, the rinse channel device may include a separate (electrical and/or mechanical) valve where appropriate.

The rinsing operation using the rinsing channel device may be operated automatically and/or manually, optionally depending on the soiling.

It may also be provided that the fitting and/or the rinsing channel device is actuated by proximity and/or motion sensors.

According to one refinement of the invention, it can be provided that the water bath or the rinse channel device comprises at least one radiation source for generating ionizing radiation. A UVC radiation source for generating UVC radiation is preferably provided.

The ionizing radiation makes it possible to further enhance the cleaning or disinfecting action of the water bath according to the invention or of the rinse channel device according to the invention. The wavelength of the ultraviolet radiation may for example be between 100 nm and 400 nm, preferably between 200 nm and 300 nm, particularly preferably approximately or exactly 254 nm.

In one development, the radiation source can be arranged in particular in the liquid outlet of the bath and/or in the profile assembly. It is also possible to provide multiple radiation sources.

The radiation source, in particular the UVC radiation source, is preferably optically shielded, for example arranged behind a cover of the liquid outlet.

In one refinement of the invention, it is also possible to provide a discharging device for filtering and discharging solids (eg contaminants such as hair or some other organic as well as inorganic matter) from the liquid.

The discharge device is preferably arranged close to the bottom of the water tank, ie close to the lower region of the water tank, or - particularly preferably - at the liquid outlet of the water tank.

As a result, solids that accumulate when the water tank is used can be filtered before entering the wastewater pipe system, which can prevent clogging of the wastewater pipe. Bacterial formation and odor generation in the wastewater pipe can also be prevented.

In one development, the drainage device is a sheet-like filter element (eg strip, mat, textile) through which liquid can flow out, while solids remain on the surface of the sheet-like filter element. ) or a film) may be provided.

1 to 4 show a rinse channel device 1 according to a first exemplary embodiment of the present invention. Geometric dimensions and relationships are to be understood as merely illustrative in the drawings, in order to explain the functional principles of the present invention.

The rinse channel device 1 comprises a profile assembly 2 , which in the exemplary embodiment shown in FIGS. 1 to 4 has a multi-part form, but in principle can also have a single-part form. As can be seen in particular from FIG. 3 , the profile assembly 2 , which should be understood as merely illustrative, comprises a first profile part 3 and a second profile part 4 . This makes it possible to simplify the production of the rinse channel device 1 .

The profile assembly 2 has at least one interface 5 for supplying a liquid (preferably water or tap water). The interface 5 has a recess 6 in the side wall of the profile assembly 2 extending along the longitudinal axis L of the rinsing channel device 1 . A liquid supply line 7 (see FIG. 5 ) may be connectable to the interface 5 .

The liquid can be directed via the interface 5 to the distributor line 8 of the profile assembly 2 . The distributor line 8 extends completely through the profile assembly 2 along the longitudinal axis L of the profile assembly 2 for distributing the liquid around the rinse channel device 1 .

In principle, it is also possible to provide an additional interface 5 for supplying liquid, for example an interface 5 on each side of the profile assembly 2 . However, preferably only a single interface 5 is provided.

The profile assembly 2 also has a distribution area 9 for dispensing the liquid. The distribution area 9 also extends completely through the profile assembly 2 along the longitudinal axis L of the profile assembly 2 . The distribution area 9 is in the form of a distribution slot extending along the longitudinal axis L of the profile assembly 2 . The distribution area 9 map is a selectively extendable diaphragm 10, for example a rubber lip (Fig. 2 shown as a dotted line). This can improve the sterility of the rinse channel device 1 .

The profile assembly 2 comprises a flow channel 11 extending from the distributor line 8 along the channel path K (see FIGS. 1 and 2 ) to the distribution area 9 . The flow channel 11 also extends through the profile assembly 2 along the longitudinal axis L of the profile assembly 2 . In this regard, the channel path K is aligned orthogonally to the longitudinal axis L of the profile assembly 2 (see in particular FIG. 1 ).

The flow channel 11 makes it possible to make the flow of the liquid dispensed from the distribution area 9 particularly uniform and laminar, which enhances the cleaning action of the rinse channel device 1 according to the invention.
